Previous radio study using 100 m Green Bank Telescope at 1.4 GHz [1]} detected a smooth diffuse structure \(\simeq \) 1 Mpc in extent, a giant radio halo, whereas a recent study showed a slightly smaller extent for the radio halo using Low-Frequency Array (LOFAR) at 153 MHz [2]}.
Similarly, previous X-ray studies led to detections of two surface-brightness peaks coincident with the two cD galaxies observed in the cluster's center.
The data indicated that the cluster is an unequal-mass merger and only one of the two cooling cores has survived the merger. The northern cluster seems to have fallen into the more massive southern cluster from the southeast, and having lost its gas content, it has now moved to its present location to the northwest. Evidence of shock with \(M\)  \(\approx \)  1.7 at \(\sim \) 140 kpc from the southern cD galaxy too is noted and the cooling flow is displaced to the southeast of the southern cD galaxy [3]}, [4]}. In this study, we report the discovery of a remnant radio galaxy in cluster A2065 using the GMRT. We also present an X-ray analysis of archive Chandra data, which enhances the interpretation of the current discovery.
